Aemetis selects Axens Vegan technology for renewable diesel and sustainable aviation fuel plant in California

Aemetis, Inc. has selected Axens Vegan Renewable Hydroprocessing technology for the Carbon Zero 1 manufacturing facility in Riverbank, California. Axens Vegan technology is designed to hydrogen treat a wide range of lipids and create a flexible shale from renewable, low density, high cetane diesel and renewable jet fuel.

The production of renewable diesel and jet is a simple two-step process. The vegan technology is based on catalysts that are developed, manufactured and provided by Axens. Source: Axens.


The “Carbon Zero 1” will produce around 45 million gallons of renewable jet and diesel fuel systems with cellulose hydrogen with a carbon intensity of below zero annually in the former ammunition plant of the Army in Riverbank, CA, with a planned plant expansion on the 142 hectare site. The cellulose hydrogen to be used in Aemetis “Carbon Zero” jet / diesel systems has a carbon intensity (CI) of -80.

Aemetis will use InEnTec gasifiers in combination with LanzaTech fermentation technology to produce ethanol, its CI negative hydrogen and by-products such as animal feed, glass and electrical energy.

The scope of Axens includes technology licenses, basic engineering, catalyst supply and proprietary equipment for the conversion of non-edible vegetable and other non-edible oils with ultra-low carbon intensity and renewable cellulosic hydrogen to produce a flexible blend of sustainable aviation fuel (SAF) and renewable diesel fuel.

Axens technology provides high yields of jet fuel while maximizing the carbon capture and sequestration value unique to the Aemetis Carbon Zero 1 project. The experienced Axens team was extremely responsive and proactive, allowing our project to progress on schedule and within our budget expectations. We believe that Axens technology is much more economically viable overall, while also having a lower capital cost than alternative technologies for producing renewable jets and diesel fuels.

—Eric McAfee, chairman and CEO, Aemetis

Aemetis recently announced a $ 2 billion airline tender and fuel mixer for the Carbon Zero 1 facility and has signed off-take agreements. Carbon Zero renewable jet and diesel fuel can be used in today’s aircraft, truck and ship fleets without any changes to fueling infrastructure or engines.

Aemetis has received $ 17 million in grants from the California Energy Commission (CEC) and the California Alternative Energy and Advanced Transportation Financing Authority (CAEFTA) to support the riverside advanced biofuel project activities.
